Update on the Week Ahead…
A shower or two still possible for Monday as a very weak system passes by. I mentioned two possible storms in my long-range from Tuesday, one for Thursday and one next Sunday. The ridge off the coast is going to retrograde back a little this week opening the storm door a little.
The PNA is strongly positive which supports ridging, but the ridge in Western Canada and near Alaska is going to try and push the jetstream South towards CA. Right now it looks like we could get hit with both storms on their Southern edge.
After nice weather on Tuesday, the first storm for Wednesday night looks to bring maybe some light snow showers above 7000 ft. and a shot of cooler air for Thursday as the sun returns. Friday and Saturday look like nice days in the 60′s as we go into Memorial Day weekend.
The models have been back and forth every day on the storm moving by Saturday night and Sunday. Anything from a big cold late season snowstorm to being missed altogether with sun all weekend. I have been biased toward the dry weather winning out looking at the teleconnections, but as we get closer I have to give the models more credit.
Right now it looks like a shot of some colder air for Sunday and the chance of rain & snow showers. The sun and warmer temps should return the following week. Stay tuned for updates on the track of the storms this week. BA
